The STONEC® Professional Line 10-Piece Screwdriver Bit Set is engineered for high-torque power driving applications across construction, woodworking, and drywall assembly. Precision-machined with dual PH2 Phillips ends, each bit effectively doubles tool service life by providing a fresh drive tip when flipped. Features a standardized 1/4-inch quick-release hex shank that locks securely into power drills, impact drivers, and magnetic bit holders. Manufactured from heat-treated S2 industrial alloy steel for high torsional strength and wear resistance, minimizing cam-out and head stripping under heavy loads. Comes organized in a durable plastic storage case within hanging blister card packaging.

Key Features & Standards
-
Double-Ended Design: Features precision PH2 tips on both ends, doubling usable lifespan per piece.
-
Industrial S2 Alloy Steel: Heat-treated for maximum core toughness, preventing tip fracture under high-torque impact driving.
-
Precision Machined Fit: Snug PH2 tip geometry reduces bit slip and fastener stripping (cam-out).
-
Universal 1/4" Hex Shank: Compatible with standard power tool chucks, impact driver couplers, and quick-change magnetic holders.
-
Convenient Storage Case: Includes a compact hard-plastic storage box to keep bits organized and protected on jobsites.
⚠️ Safety Warning: Always ensure the bit shank is fully locked into the driver chuck or quick-change coupler before turning on the power tool. Wear ANSI-approved eye protection (safety glasses) and work gloves during screwdriving operations to protect against flying debris or bit slippage.
